Appiication mea January 19, 191e. serial No. 72,984.

To all whom t may concern.:

lBe it known that I, GEORGE E. BATES, a citizen of the United States, and a resident of Syracuse, in the county ofy Onondaga and State of New York, have invented a certain new and useful Disinfecting Device, of which the following is a specication.

This invention has for its object the production of a disinfecting device particularly applicable for use in connection with the flushing apparatus of closets, lavatories, and the like, whereby a measured amount of disinfectant is delivered during each flushing operation, and preferably at the end of each flushing operation; and the invention consists in the novel combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views.

Figure 1 is a vertical sectional view of a preferable form of my disinfecting device, the saine being shown as connected to a pipe through which the water passes.

Fig. 2 is a section on line A-A, Fig. 1.

This disinfecting device comprises, generally, a container for the disinfectant, an outlet connected to the container, a measuring device in the outlet including a movable valve piece, and fluid orA water pressure operated means. for .controlling the operation of the valve piece. The valve has va receiving position and a discharge position and is normally arranged in one of said positions, and said valve is movable by gravity into one of said positions and by water pressure into the other of said positions.

In the illustrated form of my invention, the valve is movable by gravity into its discharge position. In the construction vshown in Fig. 1, the valve is normally in discharge position and is movable by back water pressure into receiving position.

1 designates the container, which may be of any'suitable form, sive and construction. 2 designates the outlet, and 3 the measuring valve located in the outlet.

The outlet is here shown as composed of a pipe section 1 integral with the base 5 of the container 1, a pipe section 6 and a coupling 7 connecting the sections 4 and 6 and having a passage in which the valve 3 slides, this passage being of less diameter than that of the pipe 6.

A portion of the valve 3 is formed hollow and provided with a port 8, which is carried by the valve into position to receive the disinfectant from the container and into position to deliver into the section 6, the valve being normally arranged so that the port 8 is in one of said positions and is movable into the other of said positions. That is, it is normally arranged in discharge position and is movable momentarily into receiving position by water pressure or back pressure in the pipe 6.

The wall of the passage in the coupling 7 serves to cut olf the port 8 from the interior of the container 1, and also to prevent the water from passing up into the container.

The upper end of the hollow portion of the valve 7 is closed by a plug 9', and a plunger 10 is movable in said hollow portion for the purpose of adjusting the space therein'. which receives the liquid from the container 1. This plunger 10 is here shown as having a threaded stem extending upwardly through the plug 9 and provided with a head 12 at its, upper end, by means of which the screw is turned for the purpose of raising and lowering the plunger 10 to vary the space in the valve and hence vary the measured amount of liquid to be delivered.

The hollow portion of the valve 3 is also formed with holes 13 for the purpose of permitting the liquid receiving space below the plunger 10 to completely ll when the plunger 10 is adjusted into a position above the port 8. That is, the holes permit the escape of air from the valve 3. These holes 13 are provided instead of a lengthwise slot for the reason that a slot would provide a by-pass around the plunger 10 which would permit Ythe liquid in the valve above the plunger 10 to pass around the plunger and out through the port 8,`so that the plunger 10 would be inoperative to regulate the amount of liquid to be delivered and the amount delivered would always be any amount contained in the hollow portion `of the valve 3 both above and below the pluner. gfalve piece between the holes 13 act as an obstruction to prevent the disinfecting liquid from passing from ,above the plunger 10 to below the same. The arrangement of this contraction at 18 is such that the stream of Water projected therethrough during back pressure in the pipe 15 from the pipe 16, strikes the piston head -V or the hollow concave portion 14 thereof and lifts the As constructed, the portions of the valve 3 so that its discharge opening 8 is cut off before generally rush of water around the head la and before the valve seats against the lower side of the plug 7, thus preventing the entrance of any water into the container.

In the construction shown in Fig. 1, the water pressure operated means is a piston head 14 located at the lower end of the valve piece and loosely fitting: the pipe section 6 of the outlet, and the pipe section 6 is connected at its lower end by means of a pipe 15 to an element 16 as a pipe through which the flushing water passes from any suitable supply as a flush tank or a main feed pipe, this element 16 having means associated therewith for creating back pressure therein so that such back pressure is transferred through the pipe 15 into the outlet pipe sec'- tion 6 in order to act 0n the piston 14 and raise the valve piece into receiving position. Then the back pressure ceases, the valve piece drops by gravity, permitting the amount of disinfectant located in the valve below the plunger 10 to pass out through the port 8 through the outlet pipe section 6, around the piston head la through the pipe 15, into the pipe 16. The back pressure may, in some instances, be due to obstructing the flowv of the water through the pipe 16, as when the closet, or other place to be flushed, is provided with perforations through which the water cannot pass as fast as it is delivered, but in this embodiment of my invention, I have shown'a deflector 17 in the pipe 16, this delector being an eXtension of theV pipe 15. This pipe 16 is usually connected at its upper end to the flush tank,

or any other supply of water. Preferably the outlet of the pipe section 6 into `the pipe 15 is contracted, as at 18, for the best working of the valve, but such contracting although preferable is not necessary.

This disinfectant device is particularly advantageous in that it is simple in construction, is readily adapted to different forms or types of flushing apparatus, and delivers the disinfectant at the end of the flow of the water instead of mixing it with the entire body of water used in flushing.

W hat I claim is A1. The combination with a pipe through which a fluid passes at intervals; of a delivery device for the4 liquid to be discharged into said pipe, said device comprising an outlet for the liquid communicating with said pipe and means for measuring` and delivering the liquid through the outlet comprising a movable member having a receiving and a discharging position and being normally arranged in its discharging position, said member having a' piston face eX- posed in the outlet toward said pipe in position to receive the back pressure from the pipe whereby said member is moved to its receiving position during the flow of fluid through the pipe and to its discharging position when the back pressure ceases to permit the liquid controlled by said member to discharge into said pipe at the end of the iiow of said fiuid through the pipe, substantially as and for the purpose described.

2. The combination with a pipe through which a cleansing fluid passes, of a disinfecting device comprising a container for the disinfectant, a pipe connected in the former pipe between the ends thereof and having an upward extension upon which the container is mounted, the extension forming an outlet for the container, a measuring device including a reciprocally movable valve located in the outlet and having a piston at its lower end arranged to be acted upon by the back pressure of the fluid in the second mentioned pipe when the fluid is passing through the first pipe, and movable thereby to carry the valve into position to receive liquid from the container, the valve being` movable downwardly upon the ceasing ofthe back pressure, to discharge-a measured amount of liquid through the outlet past the piston, at the end of each flushing operation, substantially as and for the purpose described.

3. The combination with al pipe through which the cleansing fluid passes, and means associated with the pipe for creating back pressure therein, of a disinfecting device comprising a container for the disinfectant, the container having an outletv connected to said pipe, a measuring device including a reciprocally movable valve located in the outlet, said valve having a receiving position and a discharge position and being normally arranged in one of said positions, and movable by gravity into discharge position, and a piston in the outlet and being carried by the valve and arranged to be acted on by the back pressure in said pipes to move the valve against gravity into receiving position, substantially as and for the purpose described.

1. The combination with a pipe through which a liquid passes at intervals, of a delivering device comprising a container for a liquid to be mixed with the liquid in said pipe, an outlet passage including a section having a contracted portion, and means for controlling the flow of liquid through the outlet from the container comprising a delivery member having a head movable in said section into and out of a position opposed to said contracted portion `and being normally located near said contracted outlet in position to receive the force of the stream projected through said outlet while the liquid is flowing through said pipe, and thus move the delivery member to its receiving position, substai'itially as and for the purpose specied..

5. The combination with a pipe through whichaliquid passes at intervals, of a liquid vdelivering device comprising a container for a liquid, an outlet passage leading from the container and communicating with said pipe, the outlet including an upwardly eX- tending section having a contracted portion at the lower end thereof, and means for delivering the liquid from the container into such section and through the contracted portion of the outlet comprising a delivery member movable reciprocally in said section above the contracted portion and being normally arranged in its lowermost or delivering position with its lower end opposed to said contracted portion and when in its upper position being arranged to receive liquid from the container, substantially as and for the purpose set forth.

6. The combination with a pipe through which a flowing current passes at intervals, of a disinfecting device comprising a con tainer for the disinfectant having a downwardly extending outlet connected to said pipe, and a measuring valve in the outlet arranged to deliver when in its lowermost position and to receive when in its uppermost position, the outlet having a contracted portion opposed to the lower end of of a disinfecting device having a downwardly extending outlet connected to said pipe, and a measuring valve in the outlet and arranged to deliver when in its lowermost position and to receive when in its uppermost position, the outlet having a contracted portion opposed to the lower end of the valve and the valve being arranged to deliver around the periphery thereof so that the liquid runs downwardly on the outside of the lower portion of the valve through the contracted portion of the outlet, the lower face of the valve opposed to said contracted portion being concave, substantially as and for the purpose specified.

In testimony whereof, I have hereunto signed my name at Syracuse, in the county of Onondaga, and State of New York, this 11th day of December, 1915.
